This looks pretty good, but I noticed that the light source is inconsistent throughout the sprite, mainly because some of the parts that are from the base sprites, that you then rotated, you didn't redo their shading, leaving awkward bits of shading throughout the sprite.

_________________Life isn't the kindest mistress. She will do anthing and everything to break you and to try and force you to fall victim to her cruelty. You can't, however, let her win, for when you give up and succumb to life's cruelties, that is when you die as a person. Those who keep fighting, even if they are fighting a battle they can't win, are the people who truly succeed, because success isn't measured in how well you do in the end. It's measured in how hard you fight to get to where you are.

Here's and slightly updated versionI did try to fix up the shading that I noticed. If there's anything I missed, let me know.

@Professor MorelIncorporating Venusaur was the tough part when it comes to making this sprite since I wasn't sure what part would go with this sprite and where to put it. So in the end I decided to use the parts of the leave(s) as a feathers for the wings.
